In addition, first antenna connector 404 and second antenna connector 405 are provided on the printed circuit board (PCB) (PCB) 401.The first cable 1A that is drawn antenna element 1 is connected to first antenna connector 404.Second antenna connector 405 is connected to second wireless communication module 124 via the second cable 1B.
The signal that is received by antenna element 1 is via first terminal 501 of the first cable 1A, first antenna connector 404, antenna multicoupler 403, second terminal 502 of antenna multicoupler 403 and the radio communication circuit 402 that wiring diagram 504 is transferred to first wireless communication module 123.The signal that is received by antenna element 1 also is transferred to second wireless communication module 124 via first terminal 501 of the first cable 1A, first antenna connector 404, antenna multicoupler 403, the 3rd terminal 503, second antenna connector 405 and the second cable 1B of antenna multicoupler 403.The signal of exporting from the radio communication circuit 402 of first wireless communication module 123 is transferred to antenna element 1 via second terminal 502 of wiring diagram 504, antenna multicoupler 403, first terminal 501, first antenna connector 404 and the first cable 1A of antenna multicoupler 403.Be transferred to antenna element 1 from the signal of second wireless communication module, 124 outputs via the 3rd terminal 50 of the second cable 1B, second antenna connector 405, antenna multicoupler 403, first terminal 501, first antenna connector 404 and the first cable 1A of antenna multicoupler 403.
As shown in Figure 3, second wireless communication module 124 is connected to the bus duct 302 that is configured on the system board 200.Bus duct 302 is connected to the bus 202 that is configured on the system board 200 above-mentioned.
Second wireless communication module 124 comprises printed circuit board (PCB) (PCB) 601 and the radio communication circuit 602 that is configured on the printed circuit board (PCB) 601.Radio communication circuit 602 is to be configured to according to bluetooth
TMStandard is carried out the LSI of radio communication.Radio communication circuit 602 via the edge style connector of printed circuit board (PCB) 601, bus duct 302 and bus 202 carry out with system board 200 on the communication of host apparatus (for example the USB controller in the south bridge 119, CPU111 or the like).In addition, radio communication circuit 602 is connected to the third antenna connector 603 that is provided on the printed circuit board (PCB) 601.Third antenna connector 603 is connected to the antenna multicoupler 403 of first wireless communication module 123 via the second cable 1B, as mentioned above.The through-put power of first wireless communication module 123 is lower than the through-put power of second wireless communication module 124.
In structure shown in Figure 3, antenna multicoupler 403 is installed on first wireless communication module 123 with low transmission power, and antenna multicoupler 403 is connected by wiring diagram 504 with radio communication circuit 402.Like this, only first antenna connector 404 is as the radio communication circuit 402 of first wireless communication module 123 and the antenna connector on the interface channel between the antenna element 1.So the loss and the return loss of the signal that is sent out between the radio communication circuit 402 of first wireless communication module 123 and antenna element 1 can be reduced widely.
More specifically, as shown in Figure 4, under the situation of the traditional structure that adopts antenna element wherein 1 to be shared by first wireless communication module 123 and second wireless communication module 124 by using traditional antenna multicoupler 50, three antenna connectors 51,52 and 54 are just on the interface channel between the radio communication circuit 402 of the antenna element 1 and first wireless communication module 123.Similarly, three antenna connectors 51,53 and 55 are just on the interface channel between the radio communication circuit 602 of the antenna element 1 and second wireless communication module 124.
On the contrary, in the present embodiment, as mentioned above, only first antenna connector 404 is on the radio communication circuit 402 and the interface channel between the antenna element 1 of first wireless communication module 123 of low transmission power.So the connector number on the interface channel can reduce to one from three.Therefore, when the power loss from the signal of first wireless communication module 123 can be reduced widely, individual antenna 1 can be shared by first wireless communication module 123 and second wireless communication module 124.
In addition, in the present embodiment, first wireless communication module 123 and second wireless communication module 124 are implemented as the module that is independent of system board 200, and cable 1A is used for the connection between first antenna connector 404 and the antenna element 1, and cable 1B is used for the connection between second antenna connector 405 and the third antenna connector 603.Like this, the wiring diagram on the system board 200 is not used to the transmission of RF signal.So the electronic unit on the system board 200 is not subjected to the adverse effect of RF signal.
Next, the relation between discussion antenna connector number and the loss.
The loss minimum value of an antenna connector is 0.05dB.Yet the connection status between antenna connector and the cable is depended in the variation of loss degree.In some cases, the loss of an antenna connector can surpass maximum 0.5dB.If save two antenna connectors, loss can minimumly reduce 0.1dBm, the maximum 1dBm that reduces.
In addition, because impedance mismatching, return loss just produces on the connection surface of antenna connector.Show that below return loss is owing to the adding of an antenna connector increases (measured value).
(1) return loss when the antenna connector number is one :-39dB
(2) return loss when the antenna connector number is two :-24dB
(1) value is for being connected to the measurement result of the state of measurement mechanism 800 at antenna connector 801 by cable, as shown in Figure 6.Antenna connector 801 is terminated at the resistance R of 50 Ω.
(2) value is to be connected to measurement result under the state of antenna connector 801 at the cable of another antenna connector 802 by 5cm, as shown in Figure 7.Antenna connector 802 is terminated at the resistance R of 50 Ω.
As being clear from above result, during than the outfit antenna connector, return loss increases 15dB.In addition, because the connection status between connector and the cable is also depended in the variation of return loss, return loss increases and increases along with the antenna connector number.
Because the BT module has large transmission power, it incurs loss or the adverse effect of return loss hardly.On the other hand, because the through-put power of UWB module is low, so the UWB module incurs loss significantly or the adverse effect of return loss.
In the present embodiment, as mentioned above, antenna multicoupler 403 is installed on first wireless communication module 123 with low transmission power, and antenna multicoupler 403 and radio communication circuit 402 only are connected the intervention of no antenna connector by wiring diagram.With this structure, the reduction of the signal power that sends from first wireless communication module 123 can be prevented effectively.
Simultaneously, antenna multicoupler also can be provided on second wireless communication module 124, and the 3rd wireless communication module can be connected to the downstream of second wireless communication module 124 in addition.
Those skilled in the art expect other advantage and improvement easily.Therefore, the present invention is not limited to detail and representative embodiment in this displaying and explanation aspect more extensive at it.In view of the above, can make various improvement and not deviate from the spirit or scope of the defined present general inventive concept of equivalent of accessory claim and they.
